Potato Gratin with Thyme
Directions
- Preheat the oven to 400 degrees F and butter a 1 1/2-quart shallow baking dish.
- Peel the potatoes and cut into 1/8-inch slices (a food processor is good for this). Boil in salted water 4 minutes and drain thoroughly.
- Layer 1/3 of the potatoes, 1/3 of the cheese and 1/3 of the thyme and sprinkle with salt and pepper. Repeat twice, ending with cheese and thyme.
- Heat the milk just to boiling. Whisk the egg in a small bowl and whisk in the hot milk, then pour evenly over the potatoes.
- Bake 30 minutes, until golden and the potatoes are tender.
